To all whom it may concern:

Be it known that I, Josnrn H. Moons, Jr, a citizen of the United States, and a resident of the city of New York, borough of Brook- Among the principal objects which the.

present invention has in view are: to provide a portable machine arranged to continuously mix and deliver road-building materials; to provide a machine as characterized, with means for manually controlling the distribution of the mixed materials; to provide such a machine with self-contained traction mechanism; to provide means for continuously supplying said'gmachine with. raw materials; and to provide means for measuring the raw materials for mixing.

In the drawings: Figure 1 is a side eleva tion of the rear section of a machine constructed and arranged 1n accordance with the present invention; Fig. 2 is a side ele I vvation of the forward section of a machine constructed and arranged in accordance with the present-invention; Fig. 3 is a vertical cross section taken on the line. 33 in Fig. 2; Fig. 4 is a vertical cross section taken on the line 44 in Fig. 2;. Fig. 5 is a horizontal section taken on the line 55 in Fig. 4; Fig. 6 is a vertical section taken zontal section taken on the line 77 in Fig. 1; Fig. 8 is a detail view of a mutilated driving gear employed in the present invention.

A machine built in accordance with the present invention, and when in service,c0nsists primarily of two functionally distinct parts. Oneof the parts referred to is that which may be termed the mixer, and: the other part may be designated as the spreader.-

The mixer employed in the presentmachine is of the open-trough type, wherein ahorizontal shaft 15 is mounted in bearings. The shaft 15 is suitably provided with forwardly-pitched mixing and propelling paddles 16, the purpose'of which is to cut and mix the material in a topopen trough 17. The trough 17 is semicircular in form, and its upper edges are secured to andsupported by metal channel rails 18., The rails 18 are connected at their outer ends with a cross rail 19, over which a bracket 20 is depended, to form a bearing for a reduced end of the shaft 15, Whereon is mounted a transmission bevel gear wheel 21. The shaft 15 is mounted ina bearing 22 at the opposite end thereof, and is there provided with a sprocket wheel 23. The wheel 23 is operatively connected by means of a sprocket chain 26, with a second sprocket Wheel 24, which is fixedly. mounted on the head of adrivingvshaft' The shaft 25 is mounted in bearings formed in a standard 27, as seen best in Fig. 2 of the drawings. Loosely mounted on the shaft 25 is a bevel gear wheel 28, the hub of which is serrated to form, in conjunction with a shifting collar 29, a clutch for the shaft 25. The collar 29 is splined on the shaft 25, and is moved thereon to and from the wheel 28, being normally forced toward said wheel by a spiral spring 30. The collar 29 is moved manually and by any convenient tool or contrivance. At all times, the gear wheel 28 is in mesh with a gear wheel 31 at the end of a driving shaft 32, with which the pitman 33 of the engine The elevators at each side of the machine for delivering the material to be mixed, to said trough, are likewise connected with I the shaft 25, to be driven thereby. For this 1 purpose, the ,counter-shaft 35 is provided,

on which is fixedly mounted a sprocket wheel 36. The sprocket wheel 36 is operatively nnected by means of a sprocket belt 37, with a corresponding wheel 38 on the shaft 25. The shaft 35 is operatively connected with a shaft 39, by means of gear wheels 40 and 41. In this manner,- there is imparted to theshafts 35 and 39 opposite rotation.

The shafts 35 and 39 are provided with sprocket wheels 42 and 43, respectively,

which wheels are connected, by means of sprocket belts 44 and 45, with sprocket wheels 46 and 47, respectively. The wheels 46 and 47 are fixedly mounted on shafts 48 ,whereon are mounted buckets 52. chains 51 are guided at their lower ends by and 49, whereon the lifting drums of elevators on opposite sides of the machine, are mounted. The elevator mounted on the shaft 49 is provided with a drum 50, constructed to engage and drive edge chainsT5l1,

a drum 53, which is mounted on a shaft 54 ,having bearings formed in the sides of a pit 55. The pit 55 forms the lower end of a boot 56. The boot 56 has a delivery opening at the top, communicating with a chute 57 opening into the hopper 58 for delivering grit or smalhbroken stone to a rotary measure 59, shown best in Fig. 6 of the drawings. The buckets 52 are of conventional construction and design, being adapted to lift broken stone or grit forming a part of the grout for the mixing of which the present machine is provided. The grit is delivered into the mouth of the pit 55 by means of flexible belt conveyers 60. The conveyers 60 are mounted on drums 61 and 62, the drums 61 being adjacent said pit, and the drums 62 remote therefrom. The drums 62 are mounted in bearings in sliding boxes 63, which are shifted by screws 64'employed to move the boxes 63 and take up the slack in the belt conveyers 60. The conveyers 60 extend the full lengthof the forward portion of the machine, or of that portion which is directly mounted upon the carrying wheels provided for the machine, and are designed to facilitate the. delivery of the grit to the machine without stopping the machine in its progress. With this idea in View, the grit is spread parallel to the proposed path of travel of the machine, and shovelers walk beside the machine and shovel the grit onto the conveyers 60. To aid the shovelers, back boards 65 are provided, against which the grit may be thrown. Side boards 66 form, in conjunction with the back boards 65, troughs having for their bottoms the belt conveyers 60.-

The conveyers 60 and the drums 61 supporting thesame are driven from a jackshaft 67. The $1 aft 67 and the sprocket wheel 68 thereon are connected with the driving wheel 70 on the shaft 32 of the engine, by means of a chain 69. On the shaft 67 1s a second sprocket wheel engaging a sprocket chain 72, which chain is connected with a loose-running sprocket wheel on a counter-shaft 73. Loosely mounted on the shaft is a sprocket wheel 74, which is connected by means of a sprocket chain 71, with a third sprocket wheel, which is rotatively mounted on the shaft 67, and" is rigidlyeonnected with the cup member of a friction disk clutch 76, the disk of which is rigidly connected with a clutch collar 78. Intermediate the collar 78 and the wheel carrying the chain 72 is an expansion spring, the normal action of which moves the disk clutch 76 into engagement with the cup member of said clutch. s I

At the end of the counter-shaft 73 is mounted a gear wheel 80. The wheel 80 corresponds in size to, and is engaged with a gear wheel 81, as best seen in Figs. 2 and 3 of the drawings. The wheel 81 is fixedly mounted on a short shaft 82-, on which is one of the drums 61. The shaft 73 is operatively connected with a shaft 83 by a sprocket chain-84 and sprocket Wheels 85 and 86, as seen best in Figs. 2 and 3 of the drawings. The gear Wheels 80 and 81 being of the same diameter, and the sprocket wheels 85 and 86 being likewise of the same diameter, the shafts 82 and 83 and-the belt conveyers 6O driven thereby travel at the same rate of speed, to deliver the load placed thereon by the shovelers, to the pit 55 of the boot 56. On the opposite side of the machine, belt conveyers 148 and 149 deliver the cement and sand, respectively, to the hopper 87 at opposite sides of the partition 89 thereof. These conveyers are mounted on drums 150. One of the drums 150 is mounted on a short shaft 151, which corresponds with the shaft 82 above described. A transmission gear wheel 152 is provided for the shaft 151", which is operatively connected with the shaft 73 in the manner above described with reference to the gear wheels 80 and 81. The belt conveyers 148 and 149 are furnished at their opposite edges with short angular plates 153. The standing flanges of the plates 153 pass behind the back board 154,

'against which the sand and in some insponding trough board 155 rests inside of the standing flanges of the plates 153 at the outer edges of the belts.

A clutch 77 is. splined on the shaft 73, and has a ratchet face to engage the hub of a sprocket wheel 75 loosely mounted on the shaft 73 and drivingly connected by the sprocket chain 72 with a wheel on the shaft 67. A grooved collar 79 is provided to operate the clutch 77. When the clutch 77 is engaged with the wheel 75, the shafts 73, 82 and 151 are operated to move the belt conveyers 60, 148 and 149 to perform their various functions.

The pit 87 of the boot 88 is divided by a partition 89. The partition 89 is provided to divide the cement and sand which are delivered to the rear and front of said partition, respectively, to be lifted from the bottom of the pit by buckets 90 and 91, which, in conjunction with endless sprocket chains 92 and 93, form the two elevators which are supported on drums 9-1 and 95, fixedly mounted on the shaft 48 at the upper end of the boot 88. The shaft 18, as above described, is provided with the sprocket wheel 46 connected by the belt 44 with the shaft 35, seen best-in Fig. *3 of the The sand and cement are def livered by their respective elevators to hopdrawings.

series of measuring compartments, eachseries havlng a compartment for grlt, an-

other for sand, and a third for cement. The

compartments are provided with a series of bottom plates 102, which are suitablyfastened in the compartments to vary the depth thereof, to determine the quantity of the material to be held therein. The plates are secured, removed andreplaced to conform with the specification governing the quantities of the various materials to be delivered to the mixing trough 17.

The measure 59 is provided with a shaft 103, at the outer end whereof is provided a bevel gear wheel 104. The gear wheel 104 is driven by a mutilated gear wheel 105. The, wheel 105 is a transmission member, and is fixedly mounted on a shaft 106. The shaft 106 is provided at the opposite en d thereof with a sprocket wheel 107. Said wheel is connected" by means of a'sprocket chain 108, with a small sprocket wheel 109 on the end of the shaft 35, which, as above pointed out, is driven from the shaft 25, shown best in" Figs. 3 and 4 of the drawings.

' The measure 59 is rotatively mounted.in a casing having a curved wall 110. In said casing, it is turned by successive one-quarter revolutions. These revolutions are imparted to the shaft 103 by gear toothed quartersections 111 with which the wheel 1051s provided. Between the quarter-sections 111, the sections 112 are blank and arranged to avoid engagement with the wheel 104' on. the shaft 103. The wheels 109 and 107 are relatively proportioned to impart a revolution through the.1nutilated gear wheel 105 to dump the compartments in the measure 59 into the chute 100, and from thence to the mixing trough 17. As the measure rotates, the lower edge of the front wall 113 of the hoppers 58, 96 and 97 inclusive levels the material carried over by each compartment for dumping into the ,chute 100, the surplus material remaining in. the hoppers mentioned, to fall into the next succeeding compartment; which is then filled from the hoppers, the .materials for which are being more or less constantlv delivered by elevator buckets'52, 91 and 90;" Y

drawings. between the rails 130 are rollers 134, whlch The machine is carried by driving wheels 114 and guide wheels 115. The wheels 114 are loosely mounted upon an axle 116, each wheel having fixedly mounted thereon a.

driving sprocket wheel 117. The wheels 117.

" are each operatively engaged with corresponding sprocket wheels 118 on a countershaft 119, The shaft 119 is a split shaft,

.operatively united by a differential gear mounted in a casing 120. The driving section 121 of the casing 120 is operativelyconnected by means of'a sprocket chain 122 with h corresponding driving wheel 123 rigidly connected with the wheel 74 on the shaft 73. I

The mixed materials, whenglelivered from the rear end of the trough 17, are deposited in a trough 1-24. The trough 124 is suspended in a hanging frame pivoted on stud shafts 125 and 126 by means of a truss frame, of which a string 127 and a thrust brace 128 constitute the main features. Adjacent the inner ends of the string 127. and the brace 128 is a strut 129. From the string 127 and thebrace 128 are suspended side rails 130, to which the upper? edges of the trough 124 are directly connected. The rails 130 are supported from the string and brace above mentioned, by meansof suspension bars 131, 132 and 133, vas best seen in Fig. 1 of the Supported above and extending contents of said trough from the re-- ceiving to the delivering end thereof. The belt 135 is supported at each end'of said trough by drums 137 and 138. The drum 137 is provided with a sprocket wheel 139. The sprocket wheel 139 is operatively connected by a sprocket chain 140, with a sprocket wheel 141 on a shaft-142, which is mounted on the brace 128, and is operatively connected by bevel gears, with a transmission shaft 143. The shaft 143 is operatively connected with a stud shaft 126 by means of mated bevel gear wheels 144. The lower end of the shaft 126 is provided with a bevel gear wheel 145, said wheel being meshed with the wheel 21 at the rear end of the shaft 15. i

The trough 124 and supporting structure therefor are moved about the shafts 125 and 126 as a pivot. liver the material from the delivery end of the trough 17 to the trough 124, the latter is provided with a circular hopper 146, the

To continuously desides whereof are inclined to deliver the grout to the bottom of the. trough 124, to

be moved by the blades 136 for delivery belt 135 is, by reason of the transmission mechanismabove described, consonant with I the movement of the shaft 15 and the paddles'16 mounted thereon, which operate to deliver the material from the trough 17. As the material is. delivered from the trough 124, said trough is moved in a circle about the shafts 125 and 126, to spreadthe grout being delivered therefrom. For this purpose, the pivoted structure is provided with a hand rail 147, adapted to be engaged by workmen to properly dispose the trough to regulate the quantity of material delivered to any spot on the road. a It will beunderstood that the traction mechanism moves the machine lengthwise of the road being built or repaired, and preferably. travels in the center thereof. Also, it will'be understood that the length of the trough 124; is provided to sweep to each-side of the path of'the machine a distance approximately equal'to one-half the width of the usual road. By swinging the "trough\124 to and from the opposite sides of the road, an even distribution of the material delivered therefrom is secured, requiring the minimum amount of hand-raking or grading. It will also be understood that by regulating the speedof the traction mechanism, the depth of the material delkVGI'GClfRTiH the trough 124 may be varied, for the reason that the operation of the mixer is not controlled by the mechanism controlling the traction of the machine.

The chute 100 is provided with a door 156, /which normally-closes the top of said chute, and is hinged upon/ the channel rails 18 v which support the trough 17. This door is useful, as affording means for inspection,

40 the object being to ascertain if the'materials are flowing freely to the trough 17. The

materials, as delivered from the chute 100 to'the trough 17, are in'a dry condition. \Vater is sup lied to these materials while in the trough 1 Claims:
